About Great Lakes Law
Great Lakes Law is a two-lawyer firm in downtown Sarnia, Ontario, handling real estate, wills, powers of attorney and trusts, estate administration, and business law for individuals and businesses across Sarnia-Lambton. The practice is run by Chelsea Cooper and Sarah Craig, who both grew up in the area and returned to Sarnia to practice after finishing law school elsewhere in Ontario.
Cooper studied political science and criminology at the University of Western Ontario before earning a Juris Doctor from Lakehead University's Bora Laskin Faculty of Law. Craig studied psychology and women's and gender studies at Wilfrid Laurier University and went on to a Juris Doctor from Queen's University. The firm says it aims to bring a personal connection to legal work that can otherwise feel complicated, and it has built out dedicated staff supporting its real estate, wills, corporate, and estates files.
